Not to sound like Reefer Madness — the 1936 film in which young people are driven to sad fates by smoking weed — but habitual cannabis use can cause serious side-effects, and not everyone is aware of them.

Today in The Conversation Canada, Kristen Yeh of University of Toronto discusses two of the more serious conditions that heavy cannabis can use cause: a form of cardiomyopathy that affects the heart’s left ventricle, and a condition called cannabinoid hyperemesis syndrome. “Emesis” comes from the Greek word for vomit. Combine it with “hyper” and it means nonstop vomiting.

As a chemist, Yeh researches cannabis, and is a supporter of legalization and safe use, but also believes people should be aware of all the potential risks: “The government has an obligation to ensure that information about the health risks of cannabis use is as equally accessible to the public as cannabis products have become.”

Indian activists call for recognition of queer relationships beyond marriage

Trans and queer kinships provide emotional as well as material supports and care. But legalizing marriage alone would ignore such kinship ties.
